Here is another persistent annoyance I've found with the program. Whenever I alter an image using my transform tool, by either rotating, scaling or changing perspective, etc... when I hit return to set it in place, the image always moves slightly one pixel. Every time. I had an Adobe tech share my screen and they saw this happen to my images but had no answer for this anomaly and directed me here. This has been happening to me for years in multiple versions of Photoshop.
